[QUESTION ABOUT EXTERNAL LINKS] Captions vs Comments

I have a question regarding the links in the Facebook posts and I am interested to get an answer from someone who posts links frequently and has an audience of at least 10k on Facebook.

Link in caption vs link in comments.

Any significant differences in reach/engagement?

I need to build a Real Estate page and I am interested to promote the website from time to time, but for now I just know Facebook kills the reach / engagement if you post links in captions straight away.

Thank you!

Captions in Comments For YouTube Video’s Always worked much much better for clicks- used to use Bitly to track.

how about if I post a picture and I want to redirect audience on the website?
